2 Claims. (Cl. 65-12) This invention pertains to cleaning utensils andmore particularly to crumb Scrapers, that may be carried around in thepocket and operated by nger touch.

In a particular form of finger operated crumb scraper that has beenused, the structure consists of a single piece of material curvedtransversely so that it may readily scoop up crumbs. It has thedisadvantage however of being unable to retain the crumbs gathered up ifit is held on its scooping edge against the surface, but must be tiltedbackwardly to do so.

It is an object of this invention to provide a new and improved pocketcrumb scraper that will avoid one or more of the disadvantages andlimitations of the prior art.

Another object of the present invention is to provide a new and improvedpocket crumb scraper that will tend to retain crumbs scraped up by it,effectively even while its working edge is against the surface beingcleaned off.

Other objects will become apparent as the invention is more fully setforth.

For a better understanding of the invention and other objects thereof,reference is made to the drawings illustrating herein a particular formof the invention by way of example, and to the following description,while the claims will outline the scope of the invention.

In the drawings:

Figure 1 is a longitudinal view of a pocket crumb scraper embodying thisinvention;

Figure 2 is a side elevation of Figure 1, and

Figure 3 is an enlarged sectional view of the scraper taken on line 3-3of Figure 1.

Similar reference characters refer to similar parts throughout thedrawings.

The structure of the crumb scraper shown in the drawings, consists of asingle piece of material I0, forming an arc II of about one-third of acircle, along its outside surface and with straight faces I9 projectingtangentially therefrom on both sides to form bearing surfaces forsliding along the surface to be cleaned in a right or left handedmanner. The longitudinal edge portions I2 of the crumber join with thestraight faces I9 at edge I3 and are beveled inwardly and downwardly atabout 30 degrees from said straight faces towards the inner arcuatesurface 20 'of the scraper and cause the crumbs to be gradually scrapedand raised up oif the table surface, and raised up by the longitudinaledge portions I2 and deposited in the inner arcuate surface 20, readyfor removal. The interior enlarged or humped surface I4 joins thelongitudinal edge portions I2 and inner radius 20 with a reverse curveI'I forming a restraining wall to prevent the crumbs from passing overthe inner arcuate surface 20 and out the other side of the crumber. Thehump or shoulder HI also assists the user in holding the device betweenhis fingers. The scraper may be laid on the table on its back after usewithout the crumbs coming out and will balance itself readily in thatposition. While the edge portions form a very effective scoopingarrangement, their humped construction reinforces them so the scoop orscraper is very rigid, even if made of thin and light material. The endsI5 of the scraper are preferably rounded. A suitable clip I6 is securedto the back of the scraper near one end to facilitate it being held inthe pocket of the user. It should be noted that the shoulder I'I on eachside does not interfere with the ow of the crumbs into the scraper, butforms a step that is straight and obstructive to the crumbs passingclear out of the scraper. The scraper sets evenly on the table when laidon one of its faces. The device is neat and being of pocket size avoidsthe objection which the more cumbersome dustpan offers for the same typeof duty. It is relatively light and when made of suitable material canbe very attractive.

While but one general form of the invention is shown in the drawings anddescribed in the specifications, it is not desired to limit thisapplication for patent to this particular form or in any other wayotherwise than limited by the scope thereof, as it is appreciated thatother forms of construction could be made that would use the sameprinciples and come within the scope of the appended claims.

Having thus described the invention; what is claimed is:

1. A crumb scraper of the class described arcuately formed in transversecross section with a straight scraping edge tangentially connected tothe arcuate outer surface, an inwardly and downwardly beveled raisinglip connected at its outer end to said straight scraping edge forraising the crumbs from the table up on said lip, the inner end of saidlip terminating in a curved portion forming an arcuate shoulder betweenthe inner end of said lip and the arcuate inner surface of said scraper.

2. A pocket crumb scraper comprising a single piece of material curvedtransversely throughout its length to an arc of approximately onehundred and .twentydegreea the central inner sur face of the arcuateportion being cut-away to form longitudinal enlarged shoulders and theREFERENCES CITED The following references are of record in the le ofthis patenrt:
